Meteosat Third Generation Imager instruments

The Meteosat Third Generation Imager (MTG-I) satellites carry two completely new instrument that will deliver high-quality data to improve weather forecasts: a Flexible Combined Imager and Europe’s first Lightning Imager.

The Flexible Combined Imager has more spectral channels and is capable of imaging in higher resolution compared to current Meteosat Second Generation’s Spinning Enhanced Visible and Infrared instrument.

The Lightning Imager offers a completely new capability for European meteorological satellites. It will continuously monitor more than 80% of the Earth disc for lightning discharges, taking place either between clouds or between clouds and the ground. This new instrument will allow severe storms to be detected in their early stages and will therefore be key for issuing timely warnings. Its detectors are so sensitive that will be able to detect relatively weak lightning, even in full daylight.

MTG-I also carries two smaller payloads for data collection from remote science beacons and for search and rescue by detecting emergency beacons.

The full MTG system will span more than 20 years and hence comprises six satellites, four MTG-I and two sounding satellites, MTG-S.
